CONVERTIBLE SHAFTS AND POLE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 380,806, dated April 10, 1888.

Application filed September 7, 1887. Serial No. 240,008. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. KELLY, a citizen of the United States of America, rcsiding at Greenville, in the county of Augusta and State of Virginia, have invented certain new and-useful Improvements in Convertible Shafts and Pole for Vehicles, of which the fol lowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to convertible shafts and pole for vehicles for use with a single horse or with two horses, as desired; and it consists in certain improvements in the construction of such devices, as hereinafter fully set forth and claimed.

In the accompanying drawings, Figurel rep resents a plan view of my device, showing the shafts adjusted for use with a single horse. Fig. 2 is a plan view showing the parts adjusted to form a pole for use with two horses.

Fig. 3 is a sectional plan illustrating certain details. Fig. 4 is a side view ofthe pole. Fig. 5 is a side view of a shaft. Fig. 6 illustrates the singletree attachments. Fig. 7 is a section taken on line as as of Fig. 2.

A and A designate the cross-bars, to which are secured the rear parts, B, of the shafts, the main partsB of the shafts being detachable at a, where joints are formed, as hereinafter stated. The ends of cross-bar A are made fast to the parts B by means of the clips I), the sides of each part B being reduced somewhat to receive the metal strips d, which are bolted to the rear ends of shafts B. The clips I) are fastened to the parts A and B, so as to leave spaces 0, as seen in Fig. 8, for the strips d to be passed through, the strips being slotted at 6, so that they may extend beyond the screwbolt h and secured by means of said bolt and a thumb-nut,f. The dowels g in the ends of the shafts B enter holes in the parts B when the shafts are adjusted and serve to keep the parts in line.

0 indicates singletree attachments on the cross-bar A, each of which has an eye, It, to receive a singletree and extends through an aperture in bar A, and is secured to a spring, 2', on said bar, thespring being intended to counteract any sudden forward movement of the horse. The singletrees are used when the pole adjustment for two horses is used, each singletree being passed into an eye, it, and se cured by apin, m, passed through it. A hook, to, is formed on each eye it for attaching the traces when the shafts adj ustment for a single horse is used.

I) indicates braces connected with the parts A and B, as shown.

'E indicates a pole-piece pivotal] y secured to cross-bar A midway of the same, and forming the rear partof the pole for use with two horses, the main part being formed of the shafts B, as hereinafter stated. This pole-piece when in position for use extends forward from bar A a suitable distance, with its rear end removably secured by bolt and thumb-nut to bar A. When not in use, the piece E may be detached from bar A and turned under and in line with bar A, so that it is out of the way. It is made of suitable size for the attachment of both the shafts B, side by side, as seen in Fig. 2, the slotted strips cl on each shaft extending over and under the forward part of piece E, and the dowels g entering holes in it in a manner similar to the attachment of shafts above described. The shafts B being detached from the parts B and thus applied to the pole-piece are removably secured thereto by means of bolts and thumb-nuts 19, said bolts being passed through pole-piece E and slots 0 in the strips (1. In forming the pole the shafts B are further socured to the pole-piece by means of a T-bolt, F, and a gripping-plate, q, through which the bolt extends, as shown. The head of the bolt is formed with points 1", the plate q having similar points, r, and the bolt being passed through the piece E with the bolt-head crosswise the points 1" enter holes in the upper iron strips, d. The plate q being then applied to the bolt at the lower side of piece E, as seen in Fig. 7, the points 1" of the plate enter holes in the lower strips, d, and the parts are then tightened and secured by means of a thumb nut, s.

G indicates a detachable socket and pole point, which is placed on the forward ends of the shafts B when they are brought together in forming the pole. The socket may be removably secured to the shafts in any suitable manner.

I claim as my invention-- 1. In vehicle-shafts, the detachable shafts B, provided with slotted strips 01, a perforated central pole-piece, E, pivotally connected with a cross-bar, and securing-bolts, substantially as set forth and described.

2. In combination with a cross-bar, A, the singletree attachments 0, each provided with an eye, k, and a hook, at, substantially as and for the purposes described. 7

3. In combination with a cross-bar, A, the sin gletree attachments 0, each being provided with an eye, a hook, n, and securing-pin, and connected with a spring attached to said crossbar, substantially as set forth and described.

4. In combination, a central pole-piece and detachable shafts of a vehicle, a bolt, F, pror 5 WM. H. KELLY.-
